The only water pump failure I experienced was the om606 shortly after I bought it at 220k miles. It had the blue stuff in it but I doubt it had anything to do with the coolant. The shortly there after I preventatively replaced the om603 pump at 230k miles.
Every Euro manufacturer has its own preferred coolant that a small kabal of owners swear by. Volvo's, BMW, VWs etc all do it. It's a weird cult think I'm never going to understand. Heaven forbid you try to put Mercedes coolant in an Audi or vice versa. They'll skin you alive. All cars use the same metals, seals plastics in the cooling system. There's no unobtanium in any of them.
If only putting Mercedes coolant in your Mercedes gets your rocks off, more power to you. But don't spread misinformation or lies because someone used green coolant in their car.
